Does anyone have experience with Internet Servers?

We have a small network with about 3 or 4 of us accessing the
internet for email, etc during the day. We each connect via dialup
through a phone system that limits our connections to about 32 to
34k.

Someone recommended an Internet Server (I think the brand was
Cnet) which would connect to our switch and provide connectivity to
all via the network. We would then have it connected all day long to
a direct phone line to tie up only one line instead of up to 3 or 4 for
periods during the day.

What advantages would this have over connecting one machine and
sharing the internet connection over the network?

Thanks in advance for any tips, ideas, etc.
Eric
